Hoʻohana i ka Electromagnetic Flowmeter i ka ʻoihana Pepa
2022-04-24
ʻO ka ʻoihana pepa hou he ʻoihana nui, ʻenehana, a me ka ʻoihana ikaika me ka hana nui. Loaʻa iā ia nā hiʻohiʻona o ka hoʻomau ʻana o ka hana ikaika, ke kahe kaʻina hana paʻakikī, ka hoʻohana ʻana i ka ikehu kiʻekiʻe, ka hiki ke hoʻoili waiwai maka nui, ka ukana pollution kaumaha a me ka waiwai nui.
Noho ʻo Electromagnetic flowmeters i kahi kūlana koʻikoʻi i ka ʻoihana pepa. ʻO ke kumu nui ʻaʻole i hoʻopilikia ʻia ke ana o ka flowmeter electromagnetic e ka density, ka mahana, ke kaomi, ka viscosity, ka helu Reynolds a me nā loli conductivity o ka wai i loko o kahi ākea; He nui loa kona laula ana a hiki ke uhi i ke kahe haunaele a me ka laminar. Ka hāʻawi ʻana i ka wikiwiki, ʻaʻole like me nā mika kahe ʻē aʻe. Ma muli o ke ʻano maʻalahi o ka flowmeter electromagnetic, ʻaʻohe ʻāpana neʻe, nā ʻāpana hoʻopilikia a me nā ʻāpana throttling e keʻakeʻa ana i ke kahe ʻana o ke ʻano i ana ʻia, ʻaʻohe pilikia e like me ka hoʻopaʻa ʻana o ka paipu a me ka lole. Hiki iā ia ke mālama nui i ka hoʻohana ʻana i ka ikehu a mālama pono i ka hoʻokuʻu ʻana o nā mea haumia kaiapuni.
Manaʻo koho hoʻohālike no ka mika kahe electromagnetic. 1. Lining ʻO ka mea i ana ʻia i loko o ke kaʻina hana pepa i loaʻa nā ʻano o ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe, a he nui nā mea kemika, ʻo ia ka corrosive. No laila, ua hoʻopaʻa ʻia ka electromagnetic flowmeters me ka PTFE kūpaʻa kiʻekiʻe. ʻOiai ʻaʻole kūpaʻa ka lining PTFE i ka wela kiʻekiʻe, ʻaʻole ia e kū i ke kaomi ʻino. I loko o kekahi mau kaiapuni kūikawā, e like me ka puka o ka mea hoʻokuʻu waena, ʻaʻole wale ke kiʻekiʻe o ke kiʻekiʻe, ke kiʻekiʻe ka mahana, akā e hiki mai ana kekahi mea ʻenekini i kēlā me kēia manawa. I kēia hihia, pono e koho i ka lining PFA.
2. Electrodes ʻO ke koho ʻana i nā electrodes electromagnetic flowmeter i loko o ka ʻoihana pepa e noʻonoʻo nui i ʻelua mau ʻano: ʻo kekahi ka pale ʻana i ka corrosion; ʻo kekahi he anti-scaling. E hoʻonuiʻia ka nui o nā kinikini i ka hana pepa, e like me NaOH, Na2SiO3, H2SO4 concentrated, H2O2, etc. Pono e kohoʻia nā electrodes likeʻole no nā kinikini likeʻole. No ka laʻana, pono e hoʻohana ʻia nā electrodes tantalum no nā electrodes dielectric acid ikaika, hoʻohana mau ʻia nā electrodes titanium no ka media alkaline, a hiki ke hoʻohana ʻia nā electrodes stainless steel 316L no ke ana wai maʻamau. I ka hoʻolālā ʻana o ka anti-fouling o nā electrodes, hiki ke koho ʻia nā electrodes spherical no ka mea waena i haku ʻia me nā mea fibrous no ka pae maʻamau o ka fouling. He wahi pili nui ka spherical electrode me ka mea i ana ʻia a ʻaʻole hiki ke uhi ʻia e nā mea fibrous.
